Part of the appeal of Alex G’s homespun folk pop is how unsettling it is. For every Beatles-y melody (“Mission”) or warm, reassuring chorus (“Early Morning Waiting”) there’s the image of a cocked gun (“Runner”) or a mangled voice lurking in the mix like the monster in a fairy-tale forest (“S.D.O.S”). His characters describe adult perspectives with the terror and wonder of children (“No Bitterness,” “Blessing”), and several tracks make awestruck references to God. With every album, he draws closer to the conventions of American indie rock without touching them. And by the time you realize he isn’t just another guy in his bedroom with an acoustic guitar, it’s too late.
